Peter Edward Kirtley (born 14 April 1972) is an English songwriter,[2] record producer and music entrepreneur.

He has written and/or produced for artists such as Tiësto, the Sugababes, Armin Van Buuren, Hear'Say, Newton Faulkner, Mutya Buena, Boyzone, Peter Andre, Lee Ryan, Heather Small, Kim Wilde and Alexander O'Neal.

The younger of two children, his father, Al Kirtley, was a semi-professional musician who had at one time been a member of Zoot Money's Big Roll Band and later of Trendsetters Limited, and under contract to Parlophone Records.

In 1999 he teamed up with Tim Hawes to form the writing and production team Jiant and, in the following year, they secured a track on Aaron Carter's three million selling double multi-platinum album Aaron's Party (Come Get It), two tracks on Boyzone member Stephen Gately's solo project, as well as song placements with acts in Japan, France, Denmark and South Africa.

In early 2001 Jiant reached the final of A Song for Europe,[5] but this was almost immediately overshadowed by the release of "Pure and Simple", co-written with Alison Clarkson and recorded by Hear'Say, the winners of the ITV talent show, Popstars.

[9] On 7 May 2012, BBC Radio 1 featured the official top 150 biggest selling singles of the 21st century and placed "Pure and Simple" at number 17.

[11] Kirtley continued to enjoy chart success, achieving his second number one single in the UK with the Jiant/Stargate co-production of Hear'Say's, "The Way to Your Love".

[15] In 2011 Kirtley joined with Craig Logan, former manager of Pink and ex-Managing Director of the RCA Label Group to work on his first TV format.
